yippe i have live plants in my tank with the leps and they havent toched them yet. i do use dry seaweed and cucumbers tho. so that way they dont eat the plants.

Sometimes this will work and sometimes not. The thing to bear in mind is that the fish by instinct and evolution is vegetarian, naturally eating plants. If alternative vegetable food is provided and the fish comes to "prefer" it, you may be able to save your plants. But not all specimens will act according to our wishes. The risk is there. Just like those who keep angels with neons and say they never have a problem; but many others find the angels eating the neons for lunch.

Another point is that not all plants are "tasty" and some have chemical structures to prevent being eaten. I believe I've read that nothing will eat Java Fern. But Ceratopteris in the same tank would be devoured in a minute.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
